Retinally stabilized cone-targeted stimulus delivery

Design of an integrated hardware interface for AOSLO image capture and cone-targeted stimulus delivery

We demonstrate an integrated FPGA solution to project highly stabilized, aberration-corrected stimuli directly onto the retina by means of real-time retinal image motion signals in combination with high speed modulation of a scanning laser. By reducing the latency between target location prediction and stimulus delivery, the stimulus location accuracy, in a subject with good fixation, is improv...

Perception of forbidden colors in retinally stabilized equiluminant images: an indication of softwired cortical color opponency?

In color theory and perceptual practice, two color naming combinations are forbidden-reddish greens and bluish yellows-however, when multicolored images are stabilized on the retina, their borders fade and filling-in mechanisms can create forbidden colors. The sole report of such events found that only some observers saw forbidden colors, while others saw illusory multicolored patterns. We foun...

Folate-receptor-targeted delivery of doxorubicin nano-aggregates stabilized by doxorubicin-PEG-folate conjugate.

For folate-receptor-targeted anti-cancer therapy, doxorubicin aggregates in a nano-scale size were produced employing doxorubicin-polyethylene glycol-folate (DOX-PEG-FOL) conjugate. Doxorubicin and folate were respectively conjugated to alpha- and omega-terminal end group of a PEG chain. The conjugates assisted to form doxorubicin nano-aggregates with an average size of 200 nm in diameter when ...
